            "title": "Roman Hardware Highlights",
            "description": "This video, covering the second half of 2025, opens with a person entering NASA’s Goddard Space Flight Center’s largest clean room, the Spacecraft Systems Development and Integration Facility. The room is a class 10,000 clean room with over one million cubic feet of space.The outside half of Roman, called OSD, contains the solar panels and protective layers. The Deployable Aperture Cover, which protects the mirrors during launch and then unfolds to help shield them from sunlight does a test deployment. During this test, lines connect to it and pull upward to negate Earth’s gravitational forces, which Roman will not experience in space. Then the Solar Array Sun Shield panels deploy. There are four panels that move. They fold against the spacecraft to fit inside the rocket fairing and then deploy in space to make a large flat plane that both collects light to generate electricity and helps keep the rest of Roman cool.In preparation for additional testing, technicians put a clean tent over OSD and transport it out of the clean room. They push it into the acoustic test chamber where a six-foot-tall horn projects up to 150-decibel sound at varying frequencies. The other tests are on two vibration tables that shake Roman along all three axes: up/down, left/right, and forward/backward. Engineers attach hundreds of sensors and run tests of increasing intensity. During and after each test, they carefully study the data to make sure that Roman is behaving as they anticipated.While these tests occur, Roman’s inside half, containing the mirrors, instruments and support equipment, move into Goddard’s largest thermal vacuum chamber, the SES (Space Environment Simulator). This 40-foot-tall chamber can simulate the vacuum of space and the wide temperature range that Roman will experience there: from -310° Fahrenheit (-190° C) to 302° Fahrenheit (150° C). The move to the chamber happens without a clean tent, so the entire path was cleaned, and all the workers dress in full clean-room garb to ensure that no dirt contaminates the sensitive parts of the spacecraft. Once the two layers of doors are sealed, Roman spends 72 days inside running through tests at various temperatures and with equipment turned on to ensure that it works at low temperature in a vacuum. A special array installed above the mirror projects light that engineers use to test the optics and sensors.After leaving the SES chamber and returning to the SSDIF, Roman’s primary and secondary mirrors are carefully cleaned and inspected. It is a balance to get the mirrors as clean as possible while not cleaning too aggressively and damaging the delicate surfaces. The mirrors are cleaned both horizontally with a gentle vacuum cleaner and vertically with brushes. After this cleaning, every inch is visually inspected and photographed to record the exact optical characteristics. This was the last time the primary mirror would be accessible.Finally, in late November, Roman’s two halves are joined together to form the complete observatory. The process takes the better part of a day. Two guide poles are installed on the inside half to help direct OSD down onto it. At various times, the clearances between the two halves are only a few inches. With the observatory complete, it begins preparing for another round of deployments and testing.Music credit: “Our Journey Begins,” Dan Thiessen [BMI], Universal Production MusicWatch this video on the NASA Goddard YouTube channel.Complete transcript available. || YTframe_Roman_Hardware_Highlights_SummerFall2025_3.jpg (1280x720) [473.7 KB] || Roman_HH_Summer-Fall2025_10mbps.mp4 (1920x1080) [185.0 MB] || Roman_HH_Summer-Fall2025_25mbps.mp4 (1920x1080) [452.7 MB] || Roman_HH_Summer-Fall2025_YT.mp4 (1920x1080) [880.2 MB] || RomanHHLate2025Captions.en_US.srt [588 bytes] || RomanHHLate2025Captions.en_US.vtt [570 bytes] || Roman_HH_Summer-Fall2025_ProRes_1920x1080_2997.mov (1920x1080) [2.5 GB] || ",

During SM3B a new science instrument will be installed: the Advanced Camera for Surveys (ACS). Several other activities were accomplished as well over a 12-day mission with 5 spacewalks.Four astronauts trained for five scheduled spacewalks to upgrade and service the Hubble Space Telescope during the STS-109 mission in early 2002. Three veteran astronauts, John M.Grunsfeld, James H. Newman, and Richard M. Linnehan, were joined by Michael J. Massimino, who will be making his first space flight.Scott Altman, (Cmdr., USN), a two-time shuttle veteran, commanded the STS-109 mission. He was joined on the flight deck by pilot Duane Carey, (Lt. Col., USAF), making his first space flight, and flight engineer Nancy Currie (Lt. Col, USA, Ph.D.). Currie had three previous space flights to her credit.For more information, visit https://nasa.gov/hubble.

Yet Hyperion's goals are nothing less than ambitious. The instrument is designed to gather highly complex data from a given region on the Earth by viewing the surface in terms of 220 distinct colors or 'bands' of light. Think of looking at a photograph in black and white and then comparing the exact same frame in color. Even though there is no greater resolution to the image, no change in perspective, lighting, or magnification, the amount of data presented to the viewer has greatly increased. Project managers designed Hyperion to fill in that kind of data in observed regions on the ground. The uses for an instrument than can make such fine spectral distinctions include studies of land use, changes in land cover, mineral resource assessment, research into coastal processes, changes in the atmosphere and more. || ",
